Application June 29, 1936, Serial No. 87,907

16 Claims.

This invention relates to improvements in cooky blank forming rolls and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

One of the objects of the present invention is to provide a roll for cutting cocky blanks from a mass of dough and which roll may be produced at a great savingin cost over the rolls now conventional for the same purpose.

10 Another object of the invention is to provide a. roll of this kind having an active surface defined by a plurality of die members which may be readily assembled in a manner preventing a relative separation between them.

15 Still another object of the invention is to provide a roll of this kind'where the die members of one pattern may be quickly removed and replaced by those of another pattern, thus makingit possible to produce cookies of many different patterns at a considerable saving in outlay for rolls, storage and maintenance cost.

Still a further object of the invention is to provide a roll of this kind with .a novel kind of clamping head, whereby the die. members may be tightly clamped in place upon the associated cylinder in amanner permitting a quick removal and replacement of the head when it is desired to change the pattern or design of the cookies to be made.

The above mentioned objects ofthe invention, as well as others, together with the advantages thereof will more fully appear as I .proceed with my specification.

In the drawing:

Fig. 1 is a view partly in side elevation. and partly in longitudinal section of a cocky blank forming roll embodying the preferred form of the invention.

Fig. 2 is a view inelevationof the right hand end of the roll as it appears in Fig. l.

Fig. 3 is a. view in plan. elevation of av group of die members embodied in the roll, with portions broken away better to show the structure and manner of assembly thereof.

Fig. 4 is a perspective view of one of the die members embodied inthe roll and illustrates more clearly the tongue arrangement on oneof the arcuate edges of the roll.

Fig. 5 is a perspective View of one of the die :50 members embodied in the roll and illustrates 55 scale, through the meeting or abutting arcuate edges of two adjacent die members of the roll, the plane of the section being indicated on the line 6-6 of Fig. 3.

Fig. '7 is a view similar to Fig. 6 and illustrates a slightly modified form of construction which 5 will be more specifically described later.

Referring now in detail to that embodiment-of the invention illustrated in Figs. 1 to 6 inclusive of the accompanying drawing, l indicates a hollow cylinder forming the core of the roll and upon which certain die members are mounted for internal support as will later appear. As herein shown, said cylinder has end walls I l and 12 respectively, each with ahub I3-I4 respectively through which a supporting shaft l ex- 15 tends. Said shaft may be secured in said hubs in any suitable manner as by the pins l6. That end of the cylinder associated with the end wall II is provided with a radial flange l1 and inthe inner face of which is an annular groove l8.

Mounted on the cylinder so as to surround and enclose the same are arcuate, block-like die members [9-49 each with a die recess in its external convex surface. The die members l9 have-an internal concave surface to fit snugly upon the external surface of the cylinder Ill.

As herein shown, each die member has side edges 2l-22 which are radial with respect to the axis of the shaft l5, and arcuate end. edges 23-24 respectively.- In one end edge 23 of each .block'is an arcuate groove 26, which stopsshort of the radial side edges 2I-22, in inclined shoulders 21. On the other end edge 24 of the die member are arcuate ribs 28, the outer ends of which terminate at the side edges 2l-22 and the inner ends. of which terminate as shoulders 29--2 9. These shoulders are spaced apart a distance equal to twice the distance between each shoulder 21 and its adjacent side edge 21-22 and said. shoulders 29 are inclined so as to be complemental to said shoulders 21.

As best shownin Fig; 1, the die members H! are arranged in circumferential rows about the cylinder Ill and the die members in one row are 'circumferentially offset with those in the adjacent row. With the tongue and groove arrangement shown herein, theoifset is about onehalf the circumferential dimension of each die member. Therefore, the die members in alternate circumferential rows are aligned but are offiset with respect to those in the intermediate circumferential rows, which are also aligned;

In assembling the die members, upon the cylinder, a row of such die members is placed upon ,oneend of thecylinder with the radial side edges :55

fits in the space between two ribs 28 on one of the die members to hold all members in the row against circumferential movement. The next row of die members is then applied with the radial side edges Ell-22 of adjacent die members engaged and with the two ribs 28-28 on one arcuate edge of 'each member engaged inportions of the grooves 25 in the edges 23 of two adjacent die members in the first row as best appears in Fig. 3. When the die members in the second row are assembled, it is apparent that two ribs 28 on adjacent die members in said second row, are engaged in and fill the groove 26 in the arcuate edge of one of the die members in the first row. By reason of the inclined shoulder parts 21 at the outer ends of the groove 26 and the shoulders 29 at the inner ends of the ribs 28, the assembly may be more readily made as the ribs slip more easily into place in the grooves.

In assembling the third row of die members, the procedure is as before described and the die members are then in line with those in the first row but offset circumferentially with respect to those in the second row. The other rows of die members are then successively assembled, until the cylinder is substantially enclosed or surrounded by die members.

Associated with the end l2 of the cylinder is a head 3!] including an inner annular flange 3| of a diameter corresponding to that of the die members on the cylinder. At a point on said flange, I provide one or more rib portions 32 to engage in the grooves 26 of certain of the die members. On the outer face of said head isa shallow recess to receive a plate 33 secured thereto as by screws 34. -On the'circle of said screws at points between the same, the engaging faces of thehead and plate are made to provide recesses 35 in each of which is arranged the head 36 of a screw 31. These screws turn freely with respect to the head and plate but are held against endwise movement. Thus the screws 31 may be said to be swivelled with respect to the head. The head of each screw has a recess 38 therein (see Fig. 2) in line with an opening 39 in the plate. A suitable tool (not shown) maybe inserted through the opening 39 to engage the recess 38 whereby the screw 3'! may be turned in either direction. When the screws are engaged in their threaded openings in the cylinder end l2 and turned in one direction, they draw the head toward said end I2 and force the die members into a tight, snug end-to-end engagement. This engagement in connection with the groove and rib arrangement before mentioned, is such as to securely hold the die members against relative longitudinal or circumferential shifting.

Should it be desired tochange the design or shape of the cookies to be made, the screws 31 are turned in the opposite direction and this forces the head and its plate endwise outwardly and away from the cylinder end so as to permit a complete removal thereof.- The die members now on the cylinder are removed, row-by-row and others with different shapes of recesses 20 may be assembled thereon as before described. Thereafter, the head is applied and drawn up against the cylinder end to complete the assembly.

In Fig. '7, I haveshown a modified formof structure wherein, instead of the die members being provided with the tongues on one end and the grooves in the other end, both arcuate ends of each block are provided with grooves 26a which open through the radial side edges of the die member instead of terminating short there of as in Fig. 5. Where the grooves open through said radial sides, a ring 28a is used, the ring fitting in both grooves as best appears in Fig. 7. With such a structure, when the head 30 is drawn up tight, the tight flt of the ring 28a in the grooves 26a--26a will hold the parts against re1- ative movement.

The structure of the die block member described is easy to manufacture with precision in production and greatly reduces roll cost.

While in describing the invention I have referred in detail to the form, arrangement and construction of the parts thereof, the same is to be considered only in the illustrative sense so that I do not wish to be limited thereto except as may be specifically set forth in the appended claims.
